Improvement in machines for cutting loaf-sugar

Letters Patent No. 109,295, dated November l5, 1.870.

IMPROVEMENT; IN MACHINES FOR CUTTING LOAF-SUGR.

The Schedule referred to in these Letters Patent and making part of the same.

I, VFELIX' BROWL'got" the city, county, and State ot' New York, have invented certain Improvements in Machines for Cutting Loaf-Sugar, ot' which the following` is a spccilication.

A Nature and Object.

than is now done where saws alone are used.

Figure l is a side elevation ofmy machine, with .two of the sugar loaves and carrying-tables in section.

Figure 2 is a plan, as seen from the top of the machine, and with the loaves in position for being cut into cubical blocks. p

A, A1, A2, and A represent four loaves ot' sugar to be cut into blocks, placed in oval-shaped openings in a guiding-table, B, that is 'mounted in a sliding bed, (l, which moves back and forth on. the main frame of the machine D.

Said loaves are held in position in said guidingtable` by levers or clamps l, pivoted near the center of the table B, and pressed against the loaves by the coil springs S.

Upon a projection or bracketson the inner edge of said levers is mounted a. small friction-roll to operate against an eccentric or cam, K, in the center of the guiding-table B, and in such relation to each other that when the table revolves the levers will be thrown back from the loaves, or hc permitted to close upon them, as the various operations progress.

The table B being mounted upon a central sleeve, as at E, in a hub, F, ot' the sliding bed G, has two motions, one on its own axis, seen at sleeve E, and the reciprocating motion o' the bed C.

Upon the lower end of' the axis of the table B is Va ratchet, M, with four teeth or notches corresponding to the four oval-shaped holes in the table where the loaves are to be placed, andthe pawl l engages with these notches, said pawl being attached toa cra-nkerm, which is concentric with the sleeve E of vtable Said crank-arm heilig held in a tixed position with shaft X, serves torotate the ratchet M, when the sliding 'bed O receives motion from the shaft X by the connecting-.rod t connecting with the hub F ot bed C, and a crank at the upperpend of shaft X, as at Y.

Said crank at Y must besuiciently great to move {Jhefl bed C back and forth the full diameter of the At S, iig.l 2, and underneath the table B, is arranged a gang of circular saws, so mounted on thesame shaft that they will score grooves into the loaf` as it passes over them, and said saws are raised far enough above the bed upon which the loaves slide to make scores or grooves-tothe depth ofthe size ofthe block to be formed.

A similar gang of saws is also arranged at U, working in the same plane to those at S, so that after grooves are formed in the hase .of the loaf S, and when it receives a quarter of a revolution, it is then moved over the saws at U, and similar grooves are formed, butat right angles to the previous ones.

' At Z is mounted t-he cut-oh" saw, which may be either a circular or a band-saw; but 'if circular, it should be made like a veneer-saw, so as not to waste the loaf by cutting such eurfs as is now done with the common saws.

The operation ot such amachine will nowbe easily understood.

A sugar-loafis placed'in the guiding-table B at A, and when motion is imparted to the'shaft- X by any convenient gearing from a driving shaft, as at M, the ratchet will revolve the table B suticiently far to bring the loaf A to where A is shown, or one-quarter of a revolution.

At this point the crank Y will move the bed C forward, so that were a loatl at A it would travel over the saws at S, and then another revolution wonldbe given to the table B, which would bring A1. to A?, and A2 to A, when another reciprocation would take,

place that would carry the loaf over the saws at U,

and thereby form grooves in the base of the loaf at right angles to each other, and so nearly formed into vcubes that separation from the loaf is only required,l

and this is performed by the cut-oli' saw at Z, which may be either a circular or band-saw, as alreadymentioned.

The compactness ot' suena machine, and its continuous operation without the necessity of sawing the loaves into slabs, as heretofore done, in connection with the use of very thin cut-off saws, make it superior-to anything with which I am acquainted, and, thereiore- That- I claim is- 1. 'lhe combination of saws by which grooves are formed in the loaves at right angles to each other, as described, and for the purposes set lforth.

2..lhe guiding-table B, in combination with two sets of saws, as S and U, as hereinbefore described.

3. The guiding-table B, with the sliding bed C, in combination with a cut-oit saw, a's described.
